Nibco CC00250 Socket Coupling 3 in Polypropylene Sch 80

Product Description

The NIBCO CC00250 is a 3-inch Schedule 80 polypropylene socket coupling designed for joining plastic pipe in industrial and commercial piping systems. It features a Slip x SR FIPT end connection configuration, allowing one side to accept a plain pipe end while the other threads onto a female iron pipe fitting. The black polypropylene construction provides resistance to corrosion, chemical exposure, and moisture, making it well suited for demanding wet or chemically active environments. Licensed plumbers and pipefitters typically install this fitting as part of pressure-rated drainage, process, or chemical-handling pipe runs.

This coupling is used in Schedule 80 plastic piping systems where a secure, pressure-rated socket connection is required. Typical applications include industrial process lines, chemical distribution systems, and commercial plumbing installations. The Slip x SR FIPT configuration is commonly selected when transitioning between plain-end pipe and threaded pipe components within the same run. Its black color aids in distinguishing Schedule 80 fittings from lighter-duty Schedule 40 components on the job site.

Key Features

• Schedule 80 pressure rating for higher-demand piping applications
• Polypropylene construction resists corrosion, chemicals, and moisture
• Slip x SR FIPT end connections allow socket-to-threaded transitions
• 3-inch fitting size fits standard 3-inch plastic pipe
• Black color for easy Schedule 80 identification in the field

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 80 plastic piping systems using 3-inch polypropylene pipe with Slip x SR FIPT end connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following applicable IPC and local plumbing code requirements. Depressurize and drain the piping system fully before cutting or removing any existing fittings. Use appropriate solvent cement rated for polypropylene when making socket connections, and allow full cure time before restoring pressure. Do not over-torque the threaded SR FIPT side, as polypropylene threads can crack under excessive force.
